3-Zone Tube Furnace 1700°C – TT-TF3Z-80-1700 is engineered for sintering and high-temperature heat treatment of metals, ceramics, nanomaterials, semiconductors, and powder metallurgy. Widely used in universities, research institutes, manufacturing facilities, and industries such as petrochemical and aerospace, this furnace features a high-purity quartz tube with an outer diameter of Φ130 mm and three independently controlled heating zones, each 300 mm in length. It supports continuous operation at 1100 °C with a maximum temperature of 1700 °C, powered by 380 V/50 Hz. The heating system utilizes 1500-type polycrystalline alumina ceramic fiber elements with an N-type thermocouple to deliver precise temperature control and uniform heating for advanced material processing.
Constructed from Q235 low-carbon steel, the furnace shell is corrosion-resistant and electrostatically coated, with a durable double-layer frame integrated with a heat-insulating fan system to maintain a low external temperature. The multi-layer insulation system, made of lightweight alumina ceramic fiber and premium insulation boards, is asbestos-free and minimizes energy loss. High-quality metal and ceramic heating elements arranged in ring or dual-side configurations ensure uniform temperature distribution, while three independent heating zones provide precise thermal management. The PID-controlled temperature panel with SSR/SCR output, program controller supporting up to 30 segments, heating indicators, and over-temperature alarms ensures safe, flexible, and reliable operation. A 304 stainless steel sealing flange allows vacuum or controlled atmosphere operation, compatible with quartz, metal, or alumina tubes for versatile applications.
